DiagramNode is an abstract base class from which specific types such as ShapeNode and TableNode derive. DiagramNode instances can represent graph vertices, nodes in organizational or flow diagrams, entities in ER diagrams, and so on.

The following tables list the members exposed by the DiagramNode type.
